Abstract (en)
[origin: WO2013075157A1] The invention relates to an LED projection module (1), comprising two or more LED light sources (2, 3, 4), with each LED light source (2, 3, 4) consisting of one or more light-emitting diodes, wherein each LED light source (2, 3, 4) couples light into a light guide (20, 30, 40) via a light coupling point (21, 31, 41) assigned to each LED light source (2, 3 4), and wherein light exits the light guides (20, 30, 40) via a light decoupling point (22, 32, 42) of the light guide (20, 30, 40), and wherein the exiting light is projected into the outside space by means of a projection lens (90) to form at least one light distribution. According to the invention, the light guides (20, 30, 40) for the individual LED light sources (2, 3, 4) are arranged laterally side by side in a horizontal line and directly adjoin one another or preferably form a common light guide (100) for overall light so that light can pass between the adjoining light guides (20, 30, 40), and wherein the individual light exit surfaces (22, 32, 42) are arranged adjacent one another and form a light exit surface (110) for overall light, and wherein one or more recesses (201, 202) are provided in the light exit surface (110) for overall light between the individual light exit surfaces (22, 32, 42), each of which extends at least over a portion of the vertical extent of the light exit surface (110) for overall light.
